A rolling mill has two vertical rolls 28 and 29 supported in frames 25 and 26 which are pivoted, on hinges 23, to roll housings 12 and 13 so that the rolls can be moved towards and away from a workpiece. The rolls are driven by bevel and spur gearing from a motor shaft 41, spur gears 34 and 35 being arranged so that the drive is transmitted to the rolls whatever the angular position of the frames. Rams 46, actuated by motor-driven screws 50, pivot the frames, a shaft 53 ensuring that each frame is moved the same degree. Cylinders 54 retract the frames, while tie rods 55 and 56 brace the housings 43 and 44 which contain the rams. Crossheads 47, in sliding engagement with the ends 46 of the rams, are contoured to the shape of the frames and transmit the ram pressure, although such crossheads may be dispensed with. Since the frames move in an arcuate path, the housings 43 and 44 may be made to move transversely with the ram movement. This is effected either by a crank-arm or by a cam and follower (Figs. 5-9, not shown), the cam or crank being driven from the same motor as the ram screw in each case. The roll actuating mechanism may be used for horizontal rolls or in a separate edger mill.
